Are both front and rear suspensions included with a Superlift lift kit?

Lift kits include front and rear lift components. Leveling kits do not include rear lift components.

Do you need a leveling kit in addition to a lift kit to make the vehicle level after lifting it?

In most cases, no. Our lift kits are designed to level most truck and SUV applications. This can vary with heavy duty trucks that have a tow package or heavy duty rear spring set up.

Does a lift kit lift both the front and back, and is it the same amount of lift for both the front and the back?

Our lift kits are designed to achieve a level, or close to level, stance. Depending on the application, the rear lift will be slightly less than the front.

What is the difference between the GM and Chevy bracket style kits and the knuckle kits?

The drop bracket kits utilize brackets to relocate the upper control arms and require brackets to relocate the steering assembly. Bracket style kits do not increase the front track width but do require a replacement front driveshaft. The knuckle kits use a new knuckle to span the distance between the upper control arm and lower control arm. The steering correction is also built into the replacement knuckles with the tie rod boss being higher versus the stock knuckle. Knuckle kits are easier to install but require aftermarket wheels due to the increased size of the knuckles. Knuckle kits do not require a replacement front drive shaft

Why does gas or diesel engine matter in terms of lift kit application for a given year/make/model?

Trucks with coil or leaf spring front suspensions require different springs because of the weight differences between gas and diesel engine variants.

What is the difference between Superide and Bilstein shocks?

Superlift Superide shocks are twin tube, velocity sensitive hydraulic shocks. Bilstein shocks are a mono-tube gas pressurized shock. The Superlift Superide shocks are coated with a white paint; the Bilstein shocks are a brushed steel body with a nickel and clear zinc finish. Bilstein shocks are more tuned for the application and offer more precise valving.

What is the ESC and how do you reprogram it?

To keep it easy, you don't. SUPERLIFT lift kits are designed precisely so you do not have to reprogram the Electronic Stability Control (ESC) - also referred to as electronic stability program (ESP) or dynamic stability control (DSC). In most applications that have ESC, it can not be reprogrammed.

Does the truck need an alignment after installing a lift kit?

We at Superlift will always say YES. Some of the older solid axle trucks do not have much that can be aligned but that is a rare exception.

How difficult is installing my lift kit?

Gauge complexity by reviewing the product’s installation instructions and installation notes, viewable from its landing page. The SUPERLIFT rating system uses a numbering system Rated 1-5 with 5 being the most difficult.

How will a lift kit affect my ride quality and handling?

Refer to Choosing Your Lift.

Why is front lift more than rear lift?

The majority of factory trucks and SUVs sit approximately 1.5-3 inches high in the rear, so the vehicle’s rear ride height will not be excessively low when the truck is loaded. With most people that lift their vehicles, load and towing capacity are not priorities; performance, tire clearance, and vehicle appearance are key. Contact SUPERLIFT if your lifted vehicle will be used for hauling or towing considerable loads. We may suggest a “custom build” with different rear components than what is included in the base lift kit. Refer to Choosing Your Lift.

Is a front-end re-alignment required after installing a lift?

In most cases, yes. When you raise your vehicle with a lift kit or leveling kit, you have made changes to the front end geometry - toe, caster, & camber. While these changes vary by degree in specific year, make and models, these changes need to be addresses. It is usually more noticeable when you add taller, wider tires & wheels. Re-alignments should be part of your regular maintenance regimen to ensure proper handling and tire wear. For vehicle-specific information, review the product’s installation instructions, viewable from its landing page.

How will a lift kit affect my new vehicle’s warranty?

The Specialty Equipment Market Association (SEMA), an organization that works on behalf of automotive aftermarket manufacturers, has a complete list of your rights regarding warranties and aftermarket equipment. In order to refuse a warranty claim, the dealership must be able to prove that aftermarket parts caused the issue.

How will a lift kit affect vehicle stability?

The general rule is that lifting a vehicle increases its center of gravity, although it is not unusual for moderately lifted vehicles, with moderately taller and wider tires/wheels, to be more stable than their stock counterparts; go “wide” as you go “tall”. Always drive responsibly. Take time to learn your modified vehicle’s new capabilities and limitations. Read more about Warranty Information. Most newer model vehicles are factory-equipped with an Electronic Stability Control Program; SUPERLIFT Lift Kits are compatible with the various ESC systems.

Why doesn’t Superlift offer a taller kit for my vehicle?

As suspension lift designers, we work within the limitations of the factory platform. For example, an older leaf sprung General Motors truck can be lifted up to 12”, and depending on its drivetrain, easily handle 40”+ diameter tires. Conversely, Independent Front Suspension designs are limited to more moderate lift heights and tire sizes due to their less robust steering systems and axles. Generally speaking, if Superlift does not offer a kit as tall as you think you need, you probably shouldn’t go there.

Does my state have any laws restricting lift kit height or methods?

State vehicle modification laws vary from basically none to draconian. To ensure compliance, contact your DMV, plus we suggest you reference

When should I consider changing my vehicle’s axle gear ratios?

Taller tires effectively lower a vehicle’s gear ratios, but at what point (tire size) does this become a noticeable detriment to performance and fuel economy? There is no single answer. Most vehicle models are available with different axle ratios with the ratio tied to specific engine size, whether the vehicle has a towing package, etc. If you haven’t purchased the vehicle yet, buy a vehicle with as low a gear ratio (numerically higher) as possible, other “rule of thumb” generalities… Full-size vehicles with gas engines can satisfactorily run up to a 35” tire with most factory gearing. Diesel vehicles, due to their additional torque, can satisfactorily run even larger tires.

How will lifting my truck affect my driveshafts?

Driveline correction is incorporated into virtually all SUPERLIFT lift kits. Our rear lift blocks are either tapered or flat, depending on application, to address driveshaft angle. Our replacement springs have a tapered degree shim attached, where applicable, to accomplish the same result. In certain applications, relocated differentials, are re-timed for proper angle, and to restore shaft spline engagement. Sometimes, lift block pins and holes are offset to address shaft length issues. With lifts over 6”, driveshafts may require lengthening, or driveshaft space; review the product’s installation instructions and installation notes, viewable from its landing page.

Can you lift an All-Wheel Drive (AWD) vehicle?

We do not recommend lifting AWD vehicles - they develop a driveline vibration that can't be fixed.

Lift Kit Part Numbers

The vast majority of SUPERLIFT lift kits are ordered and invoiced as a single part number with a “K” prefix. A “K-Number” identifies a specific group of components required for a given application. You will receive the appropriate components, each with their own part number, although none will bear the lift kit’s K-Number.
